Claude spots Mac USB driver dropping bytes by reading firmware in 256 KB chunks

Building a Tidbyt pixel countdown with Claude's help: backing up stock firmware failed at every baud rate until Claude read it in 256 KB chunks, revealing the Mac's driver for the USB serial chip drops bytes on long reads.
Before building, Claude also rendered three layouts with Pixlet for animated comparison — the picked design turns amber at 15 minutes and red at 5.
